Of course, that's not the really interesting rumor.is reporting that Nintendo is also planning to launch an ebook service for the WiiU. According to their unnamed sources, you're going to be able to download ebooks, magazines, newspapers, and digital comics and read them on the WiiU controller. The new service would also be available on the Nintendo 3DS, and you'll be able to share an account across both devices.
There's also talk that Nintendo's back list of player's guides might be published digitally. Most of the guides are out of print (and a lot of the games are from deceased consoles), so there's a chance that they'd be available for free. But the same can't be said for the new release Prima guides, which are also rumored to be coming to the WiiU. And Nintendo is also said to be in discussions with magazine publishers to bring a wide variety of titles to the WiiU (sports, politics, technology, entertainment, celebrities, music, cooking, and fashion).
While I could easily see the player's guides in digital form, I'm not so sure that Nintendo will launch their own reading service. It feels much more likely that Nintendo will court B&N, Amazon, and Kobo. If one of those apps were released for the WiiU, it would fill all of Nintendo's needs and cost the gaming company very little. It would also generate almost no income for Nintendo, but then again the reading service wouldn't necessarily earn much anyway.
In any case, the WiiIU won't come out for at least another 6 months, so who knows what will happen in that time.
On a related note, the WiiU is supposed to be demoed at CES 2012. But I don't see Nintendo listed as an exhibitor, so I'm not sure that they'll actually be there. I suspect that they might be at one of the outside events. I'll keep an eye out for them.
